Key specifications

How to use

Install the transceiver into a compatible 40 G multimode port on a switch, server NIC or storage interface while the host device is powered on; the hot-pluggable design allows insertion and removal without shutting down the system. Connect the transceiver to multimode fiber using the appropriate MPO/MTP trunk or breakout cable and verify link status through the host device management interface. Follow the equipment vendor’s guidelines for port configuration and diagnostic monitoring to ensure optimal link performance.

Recommendations

Use multimode fiber with the recommended connector type and ensure end-to-end fiber cleanliness. Verify that the installed cabling supports the desired link distance for 850 nm operation and consult system documentation for supported module compatibility. For critical environments, monitor link parameters via the host device and keep a spare module on hand for rapid replacement.
